To all whom it may concern:

Be it known that I, Henson A. Rmmonns, residing at .Woonsocket, in the county of Providence and State 1 of Rhode Island, have invented a certain new and use ful Improvement in Indicator-Gages, of which the following is a full, clear, and exact description.

In the manufacture of matrices it is required that certain depressions in the edges thereof shall be absolutely uniform in respect to depth. This is especially I true in respect to the character depressions, and it is also true in respect to certain V-shaped alineme'nt set or readjust the mechanism of line 4+4 of Fig. 3.

notches which some matrices have. Moreover, it is necessary that these V-shaped alinement notches be.

placed in uniform positions in respect to the bottoms of the matrices. V

The primary object of the present invention is to provide a practical gage with which to determine whether such depressions are of the correct depth. Certain features of the invention are, however, adapted for use in a gage especially organized for determining the variations in the positions of such V-shaped alinement notches. Of course, the principal purpose for which such gages are used is to determine when and how to with which said dopressions are formed. 1

The invention consists of the combinations of parts shown "in the drawing and hereinafter described and pointed out definitely in the claims.

In the drawings Figures 1 to 7 show the invention embodied in a gage especially, adapted for measuring the depth of depressions in the edges of the matrices; and Figs. 9 and 10 show the invention embodied in a gage especially adapted for determining Whether V- shaped notches in the edges of matrices are properly located and of the-required depth.

In the drawings, Fig.' 1 is a plan view, and Fig. 2 is a side elevation of a depth gage embodying the invention. Fig. 3 is a plan view, partly broken away and sectioned, of certain parts thereof near the reading scale. Fig. 4 is a vertical sectional view in the plane Fig. 5 is a vertical sectional view of a part of said gage in the plane of line 55 on Fig. 3. Fig. 6 is a vertical sectional view in the plane of line 6 of Fig; 1. Fig. 7 isavcrtical sectional view in the plane of line 77 on Fig. 6. Fig. 8ris a view partly broken away of a matrix such as the gage is designed to test. Figs. 9 and 10 are respectively a plan, and a side elevation of a modification of the invention designed espe-' end of this base is a shelf bracket B which carries a horizontal seat S adapted for the support of the matrices to be tested. These matrices are of various thicknesses, Wherefore it is desirable that this bracket shall be vertically adjustable so that the center of the depressions 5 in the edges of the matrix M may be brought into alinement with the gage point 9. As shown, there is a vertical dove-tailed tongue at Fig. 3 on the front end of the base A, and this tongue is fitted to a corresponding vertical groove on the bracket B. An adjustment screw R, which is rotatably mounted in a bracket a secured to the base, screws into the bracket B. This screw has no endwise movement in the bracket a, and therefore as it is turned it moves the bracket shelf B up or down. as required to bring the bottom of the depressions in a matrix M upon seat S in line with the gage point 9.

On the top of the bracket shelf B is a dove-tailed groove which receives a dove-tailed tongue 0 Fig. 7 on the under side of a slide C, which is supported upon said bracket shelf. A screw P, which is rotatably mounted in a flange b on the bracket B, but which has no endwise movement in its bearings, screws into this slide and furnishes the means for nicely adjusting its position relative to the gage point. On the rear end of this slide is a flange 0 whose front vertical edge serves as the base plane against which to force the edges of the matrices in order to determine the depths of thedepressions. ,The adjustment of the slide 0 is, of course,

for the purpose of bringing this base plane on the flange 0 into proper relation with the gage point. A matrix to be tested is laid upon shelf S, which in the exemplification of the invention shown, is the top of this slide so that the depressions to be measured are in line with the gage point g, and then thematrix is pushed rearward until its edge engages with said flange 0. Upon the top of the slide is a pressure slide D mounted in suitable guide ways whereby it must move at exactly right angles to said flange; and it is by the movement of this pressure slide that the matrix'is pushed against said flange, as described; The gage point g is fixed to and projects forward from a slide G mounted in a suitableguide way upon the base A." it extends over the seat S and through a notch c in flange c. It is under the influence of a spring L tending to push it forward against a stop, which may be the rear side of flange c". When a matrix M upon the seat S is moved back against the flange c, and the gage point projects into the depression m, whose depth is to be measured, this gage point g and the slide G to which it is attached is moved backward a greater or less distance, and comes to restin the position which is determined by the depth of the depressions. The variation in the position of this slide G from the required position indicates, of course, the variation in the depth of the depression; but this variation is so slight that, unless it be multiplied, it

' cannot be satisfactorily read. The device, therefore,

. the slide G a teridency to forward movement. The

other lever K is pivoted near the rear of the base plate on a knife edge I0 and its rear end is provided with a V-shaped notch k, and the rear end of the lever H is provided also with a V-shaped notch h. A knife bar N lies between the rear ends of these levers with its "sharpened ends in engagement with the said notches.

The front end of the lever K lies over a plate T, on

which is a graduated scale t adapted to be read in connection with a graduation Ia on the end of lever K.

The operation of the device will be readily understood. A matrix M having its depressions made accu-- rately in accordance with the standard may, first, be used in order that the parts may be properly adjusted, and particularly that the flange 0 may be properly adjusted with respect to the gage point. That is to say, th'e parts are so adjusted that when this standard matrix is upon the slide C, and in contact with the flange c the lever K will be at the zero point. When other matrices are put in the machine and pressed against said flange c the lever K will, by its position, indicate whether the depressions are of the proper depth, or whether the depressions are too deep or too shallow, and how much they are too deep or too shallow.

In the embodiment of the invention shown in Figs. 9 and 10, there is a slide G carrying a V-shaped gage point 9. This slide is movable in a direction at right angles to the direction in which the slide G moves, as shown in the other embodimentpf the invention. In one end of this slide G is a V-shaped notch g which .receives one pointed end of the bar Q, the other pointed end of said bar engaging in a corresponding V-shaped notch h in the side of the lever. H. This embodiment of the invention includes another lever K similar to the lever K in the other figures; and motion is transmitted to this lever K from lever H by substantially the same means and mechanism shown for this purpose in the other figure, to wit abar N pointed at both ends lying between and engaging in V-shaped notches in the two levers. In'this embodiment of the invention two slides U; U are mounted upon the bracket B. The slide U, which is supported upon the under side of the shelf of bracket B, is movable in a path parallel with the path in which the plate G moves; and the slide U may be so m0ved by means of a screw I, which screws into said slide and is rotatably mounted in a fixed arm a? in which said screw has no endwise'movement. The seat S for the matrix may be the top surface of this bracket B.

This slide U has a shoulder it which may bear againstthe end of the matrix resting upon said seat, and thereby push the matrix against a fixed flange c. This embodiment of the invention also includes a fixed flange 0 in which is the notch 0 through which the gage point 9 projects over said seat S. The slide U is movable over said seat toward and from flange c and maybe so moved by a screw 1 which screws into it and is rotatably mounted in an arm b said arm being fixed to the bracket 13 andthe screw having no endwisc movement therein. This embodiment of the invention is for the purpose of testing the position, shape and depth of the V-shaped notches m in the edges of the matrix. In order to so use it, a matrix is laid upon the seat S and is moved by slide U so that its notched edge is brought into contact with the flange c. The gage point 9 enters V-shaped notch. The matrix is then moved by means of screw I until one end thereof comes into contact with the flange c. The resultant position of the gage point 9 and the slide G to which it is secured indicates whether or not the V-shaped notch is properly located and formed. Over this slide G there is a graduated plate T, with which a lever K cooperates,-said plate and lever being like those shown in the other embodiment of the invention.
